Description

  The present invention relates to a frame joint for wooden construction in which a plurality of separately manufactured components are integrated and used at a construction site, and more particularly to a shaft joint that eliminates the need for bolts and nuts.

The applicant has proposed a joint for wooden construction that can significantly improve the previous installation work (see Patent Document 1) and can fix columns and beams without using bolts and nuts ( Patent Document 2).
Japanese Patent Laid-Open No. 9-21182 JP 2003-336321 A

  FIG. 10 (a) is an abbreviation of the joint fitting described in Patent Document 2, and is formed by integrally forming a round bar-shaped attachment portion and a flat plate-like joint portion by hot forging or casting. ing. This connecting tool is convenient for conveyance because the mounting portion and the connecting portion are formed on the same plane, and is excellent in that the mounting work is completed simply by inserting the pin member into the pin hole.

  However, since the joining tool described in Patent Document 2 does not have an abutting plane that abuts against wood and receives a load, two or more pin members are required, and the mounting strength is slightly inferior. That is, since there is no abutting plane in the connector of Patent Document 2 as in the connector of Patent Document 1 (see FIG. 10B), the load applied to the connector is exclusively inserted into the pin hole. It was necessary to support it with a pin member and it was slightly inferior in strength.

  The present invention has been made in view of the above-described problems, and can be attached by a single pin member, and it can be attached to a wooden building with a strong attachment strength. The purpose is to provide ingredients.

  In order to solve the above-mentioned problems, the present invention is used in combination with a separately manufactured body fitting and auxiliary fitting, and insert the insertion shaft separate from these into the first wood, the insertion When the shaft passes through the auxiliary metal fitting, the shaft assembly connector completes the attaching operation to the first wood, the main body metal fitting includes a contact surface that comes into contact with the first wood, and the contact surface And a flat surface that is accommodated in a mounting groove formed in the second wood, and the auxiliary metal fitting has a round hole formed therein and the abutment A column portion that is inserted into the first wood through a mounting hole formed in the surface and a head portion that is larger than the mounting hole are integrally formed.

  The first wood and the second wood are firmly fixed to each other via the shaft assembly connector of the present invention. Typically, the first wood and the second wood are fixed orthogonally, but are not necessarily limited to being orthogonal.

  Examples of the pair of timbers in which the first timber and the second timber are fixed orthogonally include a base and a column, and a column and a beam. In this case, the second timber on which the mounting groove is formed corresponds to a pillar for the base (first timber) and a beam for the pillar (first timber).

  It is also preferable that the main body metal fitting is formed in a substantially T-shaped cross section as a whole with a single flat surface and a plurality of contact surfaces orthogonal to the flat surface. In this case, the plurality of contact surfaces are arranged in a discrete manner orthogonal to the flat surface in two directions. The joint fitting having such a configuration is excellent in that the load can be distributed and received.

  Further, it is also effective that the main body metal fitting is formed in a substantially U-shaped cross section as a whole with a single contact surface and a pair of flat surfaces orthogonal to the contact surface. In this case, the pair of flat surfaces are preferably formed in parallel, and correspondingly, two attachment grooves are formed in the second wood in parallel. Such a configuration is excellent in that a wide contact surface can be taken.

  Further, as a typical example, the main body fitting is formed in a substantially L-shaped cross section as a whole by a single flat surface and a single contact surface orthogonal to the flat surface. The joint fitting having such a configuration is excellent in simplicity.

  The insertion shaft is typically a round bar-shaped pin member, and a pilot hole for driving the insertion shaft is previously formed in the first wood. Alternatively, the insertion shaft is typically configured to have a screw on the tip side and is screwed into the first wood having no pilot hole.

  In the present invention, when the insertion shaft to be inserted into the first wood passes through the auxiliary metal fitting, the mounting operation to the first wood is completed, so that bolts and nuts are unnecessary. This eliminates the need for nut tightening work, and eliminates the need to form holes in the first wood to accommodate bolts and nuts, greatly simplifying installation work and shortening the construction period. You can also.

  In the present invention, since the contact surface orthogonal to the flat surface is in contact with the first wood, the load applied from the second wood to the first wood is appropriately dispersed on the contact surface, so that sufficient attachment is achieved. Demonstrate strength.

  Moreover, since the joint metal fitting of the present invention is used in combination with a separately manufactured main body metal fitting and auxiliary metal fitting, if a sufficient amount of auxiliary metal fittings are manufactured, each of N types of main body metal fittings is necessary. Since it is sufficient to manufacture only a small amount, it is advantageous not only for inventory management but also for suppressing manufacturing costs.
